I'm beginning to notice a lot of people misremembering something about the Bulkheads of Animated and Prime. I'm going to make it clear. The Bulkheads of Animated and Prime were never military vehicles.
Animated Bulkhead turned into a police SWAT van.
Most SWAT APCs started life as military vehicles first so it's not so much a misremembering as a potential misattribution. He's paramilitary at a minimum.
That being said I agree, this is far more movie Hound than anything else.
